Secure Authentication for Web Server

A network technician is setting up a new web server on the company network.

One of the requirements for the web server is to ensure the end users can securely authenticate to the application to perform their job duties.

Which of the following ports should the network technician request from the firewall team to comply with this requirement?

A.

22

B.

69

C.

80

D.

389

E.

443

E.

The correct answer is E. 443.

Explanation:

In this scenario, the network technician is tasked with setting up a new web server that requires secure authentication for end-users to access the application. To meet this requirement, the technician needs to request a port that allows for secure communication between the web server and end-users.

Port 22 is used for Secure Shell (SSH) and provides a secure way to access a remote device. However, it is not suitable for web server authentication.

Port 69 is used for Trivial File Transfer Protocol (TFTP) and is not suitable for secure web server authentication.

Port 80 is used for Hypertext Transfer Protocol (HTTP) and provides unencrypted communication, making it unsuitable for secure web server authentication.

Port 389 is used for Lightweight Directory Access Protocol (LDAP) and is commonly used for authentication and directory services. However, it is not suitable for secure web server authentication.

Port 443 is used for Hypertext Transfer Protocol Secure (HTTPS) and provides encrypted communication, making it the best choice for secure web server authentication. HTTPS uses SSL/TLS certificates to secure communication between the web server and end-users.

Therefore, the network technician should request port 443 from the firewall team to ensure that end-users can securely authenticate to the web server application.
